TWIN BED Filed Aug. 29, 1932 2/12 3 I {a Q ,1

INVENTOR- Belmmw Levm Patented Apr. 10, 1934 UNITED STATES This invention relates to new and "useful improvements in twin beds, day beds, and similar furniture.

The invention has particular reference to the l day bed type of twin bed or other furniture which is constructed of a stationary frame and spring structure and a movable frame and spring structure adapted to telescopically engage overthe v stationary structure. In such twin beds and other furniture it is customary to upholster'the movable section and to provide an extra mattress or seat on top of the movable section which is' 28 tion substantially the entire distance of sliding except at the extreme beginning and end of the stroke which arrangement allows relative motion.

of the sections in spite of the fact that the upholstery has been sagged.

As a still furtherobject of this invention it is proposed to constructa lifting arrangement in a manner so thatit may beused as needed, and

further be adjustable'to lift the movable section to various heights as neededto overcome the de ll gree of sagging.

As a further object of this inventionit is pro posed to correct another defect of the twinbed', namely, to provide an arrangement whereby the o customary end jamb board of the stationarysecprojected.

Theftwin bed accordingto this inventionincluds a stationary frame and spring structure, adapted to rest 'upon the 'floor and being for the purposeoi receiving a mattress. This'stationary frame *and springstructure" comprises a frame consisting of'spaced' side angle irons'lO and '11 connected at the ends by end angle irons 12 and 13. These angle irons are securedupon vertical angle irons l i located at the cornersand form ing legs by which the structure may rest upon the ground. Rubber dome "shaped members 15 are that the fiooris not injured; Ajaniibboard 16 is mounted upon "the rear side'jof thejfraine sane:

- ture and .servesto close, "thefseam between: the" movable frame and spring structure hereinafter fully' described. A conventional spring structure 1'? is supported upon the angle irons 10:11, 12' and 13.

In the pastthe' jamb board ,16 hasbeeri rigidly mounted in place and I have discovered that such an arrangement is undesirable in "thatwliena.

mattress is placed upon the springstructureptha securednpon the bottom ends of the feetl lso edge ofthe mattress will engageag'a'inst theftop' edge of the jambboard 16, with the result that there is undue wearon the edgeof the mattress" in addition to the edge of the mattress being projected upwards. I overcome this defect by resiliently mounting the jamb board 16. More particularly supporting bolts 18 engage through vertical slots 19 in the jamb board and firmly engage into the frame of the bed section. Springs 20 are mounted upon the frame of the bed section and act against the jamb 16 so as to resiliently urge it upwards into a position in which the lower ends of the slots 19 engage the bolts 18. The dot and dash lines 16 in Fig. 3 illustrate a depressed position of the jamb.

The twin bed also includes a movable frame and spring structure mounted on casters 21 rest ing upon the floor and adapted to telescopically engage over the stationary frame and spring structure. This movable frame and spring structure is adapted to be upholstered at the top so as to form a seat and is useful in connection with a mattress or a seat normally on top of the movable frame structure and adapted to be placed on the stationary frame and spring structure when the bed is in the extended position. Particular attention is called to the fact that the movable sections only are upholstered and that the stationary section must be provided with a mattress which is engaged upon the stationary section when the removable section is moved to its extended position. This mattress during the day time serves as a cushion for the day bed. The jamb board 29 acts against the jamb board 16 when the sections engage each other, as clearly illustrated in Fig. 8 so as to close up the opening which would exist beneath the jamb board 29 if the jamb board 16 were not provided. The jamb board 16 is depressible only when the mattress is engaged upon the sections. At other times it seeks its raised position.

The movable frame and spring structure comprises spaced side angle irons 22 and 23 joined at the ends by end angle irons 24 and 25. At the corners the angle irons 22, 23, 2 1 and 25 are rigidly secured upon vertical angle irons 26 also constituting feet for supporting the structure. In all there are four corner angle irons 26 and on the bottom of each of these there is one caster 21 so that the movable frame and spring structure is supported, in all, upon four casters and is adapted to be pushed readily along the floor.

The casters 21 are arranged so that the movable frame and spring structure is adapted to move forwards and rearwards relative to the stationary frame and spring structure. On the front side and upon the ends of the movable frame and spring structure there are secured boards 27 and 28, respectively, which are used in the upholstering of this section. Upon the rear side there is a small jamb board 29 secured upon the angle iron 22. This jamb board 29 is adapted to cooperate in conjunction with the jamb 16 for closing the seam when the sections of the twin bed are collapsed. Examining Fig. 2 it should be noticed that the jamb board 29 will abut against the jamb board 16 when the sections of the twin bed are collapsed and therefore the jamb board 16 acts as an abutment to limit closing of the sections of the twin bed.

Particular attention is called to Figs. 1, 6 and 7 where it should be noticed that the angle irons 23, 24 and 25 are turned with their flat sides on the top while the angle iron 22 is turned with a flat side on the bottom. A customary spring structure 30 is secured upon the angle irons 22, 23, 24 and 25. To add rigidity, braces 31 are secured on the corners of the angle irons just mentioned. The upholstery of the movable frame and spring structure is not shown on the drawing nor described in this specification since it forms no part of the invention but it should be borne in mind that the upholstery will sag downwards and so strike against the stationary frame and spring structure when these sections are moved relative to each other.

In Figs. 1 and 2 the two sections of the twin bed has been shown separated for illustration purposes only. These sections are normally held against separation by the arrangement of catches which comprise hook elements 33 secured upon angle irons on one of the sections and adapted to engage in extended positions of the section against hook elements 34 on the other section and so limit motion of the sections to the open position only. The hook elements 33 are detachable, since they are merely held by bolts 35 which allows for the complete separation of the sections.

It is customary to provide means for guiding the sections of the twin bed in their motion from the closed to the open positions. This means customarily comprises tracks in the form of angle irons 36 secured upon the sides of one of the sections, as shown on the drawing upon the sides of the stationary frame and spring structure section, and coactable with a pair of casters 3'7 secured upon the other section. are attached upon one of the arms of the angle irons 26 and arranged so as to be engageable upon the irons 36 and so guide sliding of the sections. For this purpose a portion of the rear arms of the angle irons 26 are cut away, this portion being located between the dot and dash lines 37 which allows the angle irons 36 to slide in tele scopic relation into the movable frame and spring structure as indicated by dot and dash lines in its position within the other bed sections.

A main feature of this invention is an arrangement of means associated with the bed section for lifting the movable frame and spring structure section relative to the stationary one during substantially entire relative sliding of these sections F11.

except at the extreme end. Thus when the sections are closed they are in their natural positions and also when completely opened. But at intermediate positions the movable sections is lifted relative to the stationary one so that sagging of the spring structure 30 does not interfere with the relative moving of the sections. The particular means referred to, is detachable so as to be used only when it becomes necessary. In detail this means comprises an arch member 38 formed from laminations 39 which are removable and so allow control of the height of the arched members. The detachable mounting of the arched members is obtained by the provision of screws 40 engaging through the laminations of the arch members and threadedly into the bottom of the angle irons 36. The arrangement allows use of the twin bed merely with the tracks 36 acting directly against the casters 37. When sagging of the spring structure 30 takes place the arched members 38 may be secured in place upon the tracks 36 and slightly lift the movable section relative to stationary one to overcome the defect. When further settling or sagging takes place additional laminations are added and so the defect of sagging overcome. This construction increases the life of the twin bed materially and eliminates frequent reupholstering.
